ChEBI: Ammonium acetate is an ammonium salt obtained by reaction of ammonia with acetic acid. A deliquescent white crystalline solid, it has a relatively low melting point (114℃) for a salt. Used as a food acidity regulator, although no longer approved for this purpose in the EU. It has...
The addition of 5% methanol to the reaction substantially increases the quality of the spray and can be required to obtain acceptable spectra; presumably other organic solvents miscible with water could be used, but methanol has the advantage of low cost. Typically, the enzyme is prepared in ...
The reaction of aromatic aldehydes, dimedone, and malononitrile in the presence of ammonium acetate has afforded tetrahydrobenzo[b]pyrans instead of polyhydroquinolines under both grinding and reflux conditions; thus ammonium acetate acts as a catalyst for this transformation instead of a reactant. ...
Ammonium carbamate, with the chemical formula NH4CO2NH2 and CAS registry number 1111-78-0, is a compound known for its role in various chemical reactions. This white crystalline solid is formed by the reaction of ammonia and carbon dioxide. It is commonly used as a precursor for the ...
